“…Sep is a hydrated magnesium clay mineral of fibrous morphology with Si 12 O 30 Mg 8 (OH,F) 4 (H 2 O) 4 ·8H 2 O as the unit cell formula. Apart from the fibrous macroscopic and high specific surface, rich reserves and low cost are also well known [32–34]. On the basis of the above features, Sep has been paid much more attention in the world and many have started to attempt using Sep in electrode material research.…”

Natural sepiolite (Sep) nanofibers were coated with carbon and nanoscale SnO2 to prepare an emerging nanocomposite (SnO2–C@Sep), which exhibited enhanced electrochemical performance. Sepiolite could act as a steady skeleton, carbon coating principally led sepiolite from an isolated to an electric state, and decoration of nanoscale SnO2 was beneficial to the functionization of sepiolite. Cycling performances indicated that SnO2–C@Sep showed higher discharge capacities than commercial SnO2 after 50 cycles. The nanocomposite SnO2–C@Sep possessed enhanced lithium storage properties with stable capacity retention and low cost, which could open up a new strategy to synthesize a variety of functional hybrid materials based on the cheap and abundant clay and commercialization of lithium-metal oxide batteries.

It was found that a modified natural sepiolite material could tremendously catalyze the chemiluminescence (CL) emission of the luminol-H 2 O 2 system. A variety of characterization methods, including FTIR, XRD, SEM, BET and CL spectroscopy, were utilized to investigate the possible CL enhancement mechanism. Moreover, a modified natural sepiolite was used for the luminol-driven CL detection of H 2 O 2 . Under the optimum conditions, the CL intensity was proportional to the concentration of H 2 O 2 in the range from 0.01 to 8 mM. The detection limit (S/N ¼ 3) was 8.8 nM and the relative standard deviation (RSD) for twelve repeated measurements of 1.0 mM H 2 O 2 was 2.5%. The proposed method was also successfully applied to detect H 2 O 2 in tap and rain water samples with recoveries of 98-104%. Thus, this method can be used as a sensitive detection tool for the analysis of H 2 O 2 .

In this study, poly(vinyl alcohol) (PVA) nanocomposite fiber mats with sepiolite were prepared via electrospinning technique. The measurements of fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), contact angle, scanning electron microscopy (SEM), and atomic force microscopy (AFM) were used for the characterization. The effect of polymer/sepiolite ratio and heat treatment on the properties of samples was investigated. The heat treatment which decreased the solubility of nanofibers and the addition of sepiolite resulted in a decrease in nanofiber diameter, contact angle with water, and water drop spreading rate on the material, and also resulted in an increase in water drop spreading rate inside the material.
